VBA Excel: Problem w/ Loop
 

Hi,


I am trying write an excel macro that will prompt the user to choose a
number between 1 & 128, beginning from 64 the user will choose whether
or not the number they have chosen is higher or lower until the number
is selected.


However, I would like to write an exception statement (error statement)

where the vba interpreter prints an error message if the user's chosen
number is inconsistent in other words the person is dishonest about
their guess. This should happen in less than 7 guesses or less.


But I cannot get it to work. Please instruct me on how best to rewrite
this script.


Code:
------------------------------*----------------------
Sub Guess()
Worksheets("Sheet1").Range("A1*:IV65536").ClearFor mats
Worksheets("Sheet1").Range("A1*:IV65536").ClearCon tents
Columns("A:IV").ColumnWidth = 10
Dim Hi As Integer
Dim Lo As Integer
Dim Guess As Integer
Dim NoGuess As Integer
Dim Ans As String
Hi = 128
Lo = 1
NoGuess = 0
Ans = ""
Resp = MsgBox("Pick a number from 1 to 128 and click on OK when you
have it", vbOKOnly)


Do Until (NoGuess = 8)
NoGuess = NoGuess + 1
Guess = (Hi + Lo) / 2
Range("A1").Value = "My Guess: Number "
Range("B1").Value = NoGuess
Range("C1").Value = " is "
Range("D1").Value = Guess
Ans = InputBox("Please Enter hi, lo or eq", "Hi", "eq")
If Ans = "hi" Then Hi = Guess - 1
If Ans = "lo" Then Lo = Guess + 1
If NoGuess = 8 Then
Range("A2").Text = "Error: Your guess must remain constant until end!"
Columns("A:E").AutoFit
Loop
End Sub
